Hi all,
I have set up a PPPoE connection using ``ppp'' on a FreeBSD 4.3-RELEASE
system. The funny thing is, my tun0 interface is gathering IP addresses.
At every disconnect, the old IP address of the interface is maintained so
after a few network quirks, the interface is loaded with addresses:
% ifconfig tun0 | more
tun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1492
inet 62.234.21.18 --> 255.255.255.255 netmask 0xffffffff
inet 62.234.20.186 --> 255.255.255.255 netmask 0xffffffff
inet 62.234.20.162 --> 255.255.255.255 netmask 0xffffffff
inet 62.234.20.119 --> 255.255.255.255 netmask 0xffffffff
inet 62.234.20.117 --> 255.255.255.255 netmask 0xffffffff
inet 62.234.20.196 --> 255.255.255.255 netmask 0xffffffff
inet 62.234.20.23 --> 255.255.255.255 netmask 0xffffffff
inet 62.234.20.51 --> 255.255.255.255 netmask 0xffffffff
[...]
inet 62.234.25.227 --> 62.234.24.1 netmask 0xff000000
% ifconfig tun0 | wc -l
249
This is a fun sight, ofcourse, and it does not seem to harm the connection
itself because I will never try to connect to one of the old IP addresses
anyway, but I have to restart ppp to get rid of the lot of addresses.
My configuration is pretty straightforward from the handbook. Am I making
a common mistake?
Thanks!

----------------- from /etc/rc.conf
[...]
ifconfig_ed0="up" # pppoe interface, only needs to be up
ppp_enable="YES"
ppp_mode="ddial" # dedicated + redial if dropped
ppp_profile="wanadoo"
ppp_nat="YES"
[...]
----------------- /etc/ppp/ppp.conf
default:
set log Phase tun command
set ifaddr 10.0.0.1/0 10.0.0.2/0
wanadoo:
set device PPPoE:ed0:wanadoo
set authname myname@wanadoo
set authkey mykey
set dial
set login
add default HISADDR
nat enable yes
